That's not "teaching kids to think like scientist." Only a quack scientist would limit their study of "climate" to "recent decades." True scientist would study hundreds and thousands of years.
“...she’s learned that in recent decades, the snowpack in the very spot she and her classmates dug into has trended downward.”
She just digs snow one day and that tells her the snow trend... over the last decades.
Very “scientific” indeed, according to leftist logic.
